Answer:
The system has no solution
Explanation:
You can check it graphically, the pair of equations represents two lines, if they never cross, or if they are parallel, the system of equations is inconsistent and has no solution.
I attached you two pictures in which you can see the graphical result.
An example is free fall ,
Answer:
Upward
Explanation:
For charged particles immersed in an electric field:
- if the particle is positively charged, the direction of the force is the same as the direction of the electric field
- if the particle is negatively charged, the direction of the force is opposite to the direction of the electric field
In this problem, we have an electron - so a negatively charged particle - so the direction of the force is opposite to that of the electric field.
Since the electric field is directed downward, therefore, the electric force on the electron will be upward.
Answer:
Power, P = 30 W
Explanation:
We have,
Voltage drop of a circuit is 60 V
Resistance of the resistor is 120 ohms
Current across the circuit is 0.5 A
It is required to find the power conducted by the resistor. Power conducted by a resistor is given by :

V and I are voltage and current

So, the power conducted by the resistor is 30 watts.
Answer:

» 30 N
Explanation:
<u>Given</u> :
Mass → m → 6kg
Acceleration → a →

<u>To</u><u> </u><u>find</u> :
The formula for force
F = m • a
F = 6 • 5
F = 30 N
